Abstract
Winglets are small aerodynamic structures attached to the front fairing of a racing motorcycle to increase traction. It increases the control of the rider and maneuverability while accelerating as it reduces the event of front wheel lift. This paper discusses the speed of the motorcycle and braking force given by the rider. Based on the inputs it would change the orientation of the winglet which would produce a drag force on the bike and increases the rate of deceleration. CFD simulation is performed by STARCCM + software with unstructured polyhedral mesh and AKN k-ε turbulence model is used on the winglet surface with different orientations (0 and 90 degree) to find the type of airflow that creates optimum drag and maximum pressure, in which winglet can withstand without being damaged. The procedural way of numerical approach and it results may provide design assistance for the improvement of the aerodynamic winglets for racing motor vehicles.
